Mohamed Salah, Roberto Firmino and Alisson Becker have joined up with the Liverpool squad in France.
The returning trio were put through their paces by Jurgen Klopp alongside the rest of the Reds players at the Evian training camp while Naby Keita and Xherdan Shaqiri also joined in after returning from injuries.
Attackers Salah and Firmino and goalkeeper Alisson are yet to play a minute of action this pre-season after enjoying some time off following their international commitments for Brazil and Egypt.
The squad means Liverpool are now just Sadio Mane short of a full complement of players as the pre-season plans take a considerable step up in intensity during the training camp.
Mane will return to Melwood on August 5 and could be in contention for the visit of Norwich later that week, although the Senegal star may be named on the substitutes' bench for the Premier League curtain-raiser, given his late comeback to Merseyside.
Liverpool meet Ligue 1 side Lyon in Geneva on Wednesday evening before returning to Merseyside later in the week ahead of the Community Shield at Wembley on Sunday afternoon.
Evian squad: Trent Alexander-Arnold, Alisson Becker, Rhian Brewster, Bobby Duncan, Harvey Elliott, Fabinho, Roberto Firmino, Joe Gomez, Jordan Henderson, Ki-Jana Hoever, Naby Keita, Adam Lallana, Yasser Larouci, Adam Lewis, Andy Lonergan, Dejan Lovren, Joel Matip, Simon Mignolet, James Milner, Jakub Ojrzynski, Divock Origi, Alex Oxlade-Chamberlain, Andy Robertson, Mohamed Salah, Xherdan Shaqiri, Sepp van den Berg, Virgil van Dijk, Gini Wijnaldum, Harry Wilson.
